In recent weeks the results (announced by press release) of 2 major placebo-controlled randomized trials—ZEUS, testing an interleukin-6 (IL-6) blocker vs inflammation, and HORIZON, testing a drug to lower Lp(a), indicated failure to achieve their primary endpoint.Are we maxxed out for new treatments vs heart disease, as this article in the WSJ (←gift link) today asserts? “Cardiovascular drug development is starting to look a bit like the modern oil industry. The easy wells have been tapped. What’s left is in deep water: expensive, technically perilous and less likely to strike oil.”Or is it more complicated? Are the trial results and reasons for failure different?I wrote a recent Ground Truths —The Coronary Artery Inflammation Controversy— on the data (what has been released to date) and my take. But I wanted to vet this with another physician-scientist who is studying atherosclerosis and turned to Prof Marios Georgakis, from the University of Munich, who as I mentioned in the previous piece, wrote a brilliant analysis of ZEUS and is also doing writing about HORIZON.Many years ago we went through a “CV winter” when the biopharma companies largely shunned doing clinical trials for heart disease. They thought the field had been maxxed out. After a lapse of several years, there have many trials undertaken with positive results and substantial progress for better treatments vs heart disease. Both Marios and I remain optimistic that we are a long way from maxing out, as you’ll learn from the podcast. Heart disease is the number one global killer, for both men and women. That’s despite all the progress that has been made to date.Thanks for your support of Ground Truths and to Dr. Julie Kellogg, Vau Geha, Ralph Horwitz, Jessica Coffman, Michael G.
